When I try to run my hydrographs through a pond I get an error stating something to the effect of: Outflow greater than Inflow on Hydrograph 6 for the 50-yr storm.
How can the outflow be greater than what is flowing into it? How the program can calculate this.
why my model shows an event mean storage of 20396 cf when I don't have any storage nodes? How is the model storing that amount of water? I'm thinking this is why my total inflow doesn't match my total outflows?

Where is the best place to view the results for the detention pond peak outflow and maximum HGL?
Also, the program seems to separate the results per year storm...anyway to view the results for all year storms in the same report?
how do you attach the .spf file?

I had a request come in this morning to generate a spread sheet with all PI's along a route with angles greater than 20°s. Using Civil 3d 2011 I thought the PI station report or any of the reports for that matter would tell me the turned/deflection angle for each PI. However, I have discovered I can get coordinates, bearings etc. but no angles. How to spit out a PI report showing the turned angle for each PI?

View 1 Replies View RelatedNew user for civil 3d and the hydraflow extension for civil 3d. I have my pipe network created, all the correct catchments are attached to the correct basin/inlet. i have opened my network in hydraflow and am ready to run it. when I click run it says no flow. Now I know there is another step i need to set my flow wth TOC, I've inputted that, i am using the standard idf curve hydraflow, i have the areas with their coefficients, however it is not calculating my flow rather it is telling me no flow is inputted for certain lines i.e. the ones with MH connections and no inlets.
I have attached my .stm file to this thread, i changed the extension so it would post, just delete the .doc from the extension and it should work in your hydraflow.
I opened Hydraflow Sewer Extensions and created a project. I was able to save it and open repeatedly without problems. I opened open project dialogue window here I copied and renamed a copy of the project file. When I tried to open either the original file or the renamed version - Hydraglow shuts down. The project file has attached dxf file as abackground. (see attached). I hate to lose a day of data entering given my tight deadlines.
View 3 Replies View RelatedI can't seem to confirm the discharge table that hydraflow produces in hydraflow hydragraphs. I think I understand the equation itself (it's been a while since I took hydraulics), but can't understand where I'm making my error (if I am). Normally I trust the stage/discharge curve that hydraflow produces, but the City Engineer is asking me to confirm the values by hand and show them on the plans. Is there a link to an detention pond example that shows how a curve (the outflow values) was generated (confirms the discharge table at various elevations)? The equation is on page 85 of the users manual.

Everytime I try running an analysis I get the following message: Line 1, 2, 3 has no flow. Check pipe size(s) and slope(s). Then the program closes up.
View 1 Replies View RelatedI am trying to get the cut volumes for areas that are greater than 15ft of cut for my project. We know that we will be able to get the top 15 feet with heavy equipment but will be drilling and blasting anything greater than 15 feet of cut. This is a different pay item, with greater cost so we need to quantify it.
I've got a composite surface that graphically shows me the elevation bands so I can see the areas that are greater than 15 feet but I'm not sure how to quantify the volumes.
Currently using C3D 2012 with the volume dashboard extension. Have 2013 installed just haven't jumped over yet.
Is there anyway that a tidal flap valve fitted to a culvert outlet can be modeled in Hydraflow Express Culverts.
View 1 Replies View Relatedone would think that you could just export the .stm file into hydraflow, make some changes, and import, and all would be fine. when i export, all of the structures in hydraflow come up as drop curb. how can they come in as what they actually are.. aka, when the part i use is a 2x4 box, it should come into hydraflow as a "grate inlet", or a st-mh will come in as a "manhole".
and then likewise, when the changes are made, and its brought back into autocad, they all come in as a "standard" style. except the outfalls, which show as a "standard" style, but come in with a different block, and get a whole new label (outfal - x)

View 5 Replies View RelatedI am having issues with importing / updating existing storm network.
The problem is when I update the storm network, All the outlets are added as new structures. It does not update the existing headwall / end sections.
I then have to go thru and delete the added (null) outlet structure. Then, reattach the existing outlets to the pipe network to show up in the structure data table correctly.

During an import event I get a warning message saying the Angle is out of Range. The .fbk text below is where the import is getting hung up, the red text is the specific line.
F1 VA 23211 260.52200 84.640 90.32060 "HWC1"

Shortkey to turn off the warning and pop up messages? for instance, "one object has been changed to a frozen or turned off layer".

There does not seem to be a real problem because I can open the exported drawing in vanilla AutoCAD OK, (although I do still get a proxy notice..?).
A few other older threads about this reveal no solution or confirmation that this dialog is a bug.

why I'd get this error when doing an Export to AutoCAD 2010/2007/2004...? It seems to be innocuous, and irrelevant, but it's disturbing none-the-less. I haven't been able to identify any reason why it appears, and all drawings seem to work normally, with no problems. AUDITs turn up no errors. So I've just been ignoring this message, but it's distracting. And it doesn't always appear... although I haven't been able yet to identify what causes it to appear in some drawings, and not others. I think it only ever happens when there's an XREF, but not sure... (Maybe when an XREF is in an older version of C3D/LDD/AutoCAD...?)

View 6 Replies View RelatedI am running Windows 7 Professional 64 bit, plotting to HP 4500 DesignJet. If I attempt to plot an oversized map the plotter either spits out a blank page or says it plotted the map and no map prints. We have another machine running Vista 64 bit and Map 3D 2011 and it is able to plot just fine. Another machine is running XP and Map 2008 and can plot fine.
I have updated plotter drivers, settings, and I have tried plotting off several .pc3 configurations all ending with the same result. As of right now when I need to plot large maps I have to send an e transmit to my other machine in order to plot, which just isn't going to work.
Is there any way possible to have an angular dimension to denote an angle of greater than 180 degrees?
View 4 Replies View RelatedIs there a way to enter the greater than or equal symbol into a block attribute value...?
For example...TEMP IS >= 20O F
** I have found this problem still exists ranging from AutoCAD 2007 - 2010 **
I'm trying to insert the "greater than or equal" symbol in an MTEXT box. Normally, I just grab the old trusty Character Map utility in Windows to find my symbol and copy/paste into the bext box. The funny thing this time is that it forces the font to be Arial (I'm using Simplex on all my MTEXT objects). Here's something else strange: If I change the font in Character Map to Simplex, there ISN'T a greater than or equal symbol but there IS a less than or equal symbol!
So the next thing I tried was a straight Unicode entry in MTEXT. I first tried "U+2264" for less than or equal and got my nice, simplex symbol but entering "U+2265" still forces an Arial font! Is this simply the way it is or am I missing something here?

View 5 Replies View RelatedI am trying to output a project at higher than 30fps and I am failing miserably. My camera can create 1080 mp4 files at 30fps or 720 mp4 files at 30 or 60fps. I want to creat a video using 720 at 60fps (or near to it).
If I load a 60fps clip and play the clip it runs at the original frame rate. If I play the project however, it plays at 25fps. I have tried to change the project properties, but I cannot select anything higher than 25fps in mpg (or 30fps in avi). Likewise, when I create a video file I am stuck at the lower frame rate. Although I am happy with the 1080X30fps clips and projects; it defeats the object of having a faster camera.
if there are any digital cameras which do image capture with greater than 8 bits per channel? I don't doubt such a camera would be well out of my price range, but I've got into scanning and working with with 16-bit colour and I've got the itch...
does anyone here regularly work in a 16-bit colour space?
